Interesting Exhaust Design with exhaust evacuation/booster
Hi Guys, I have been in contact with Dave Carpenter in the USA who races Pro 4 Series speedway car powered by a 2.0 Pinto making around 230 odd hp. (http://www.secordmotorsports.com/) to pick his brain on a few things and he sent me a few pics on this exhaust system he is playing around with. To Quote Dave "Matt..... the pic's are a header system designed/run on a 2.0L Pinto road engine up here in the States. Note the last picture. An exhaust evacuation/booster device we designed in order to pull a vacuum inside a wet-sump engine. Installed inside the 3" header collector. We'll have some actual vacuum number's on the engine in about 1 month. Pass the pic's around down there..... if you like." Any comments would be great. I have sent this thread link to Dave so I'm sure he'd be happy to answer any questions. Here's a few pics. Cheers Matt 1.1
